As shown in the Figure, while the arm is rotating about point O , a motor is driving the platform rotating it with respect to the arm, at the other end of the arm at point A . At the instant shown, on the platform a ball B is rolling away from point A , with the velocity and acceleration relative to the platform as indicated in the figure. Determine
a) The velocity of the ball with respect to inertial reference frame xY.
b) The acceleration of the ball with respect to inertial reference frame xY.
